I try as promised, but here a short overview:

Missing:
USB(-OTG)
LCD
EMAC
MEM (external memories for STM32F103 devices)

Working:
USART
I2C
GPIO
ADC (single conversion and DMA conversion)
PLL (autoconfig at boot, config via nutconf)
TIM (basic timer functions, some still stmlib state)
FLASH (self flashing, confnut/confnet in flash)

Partly:
CAN (only hw-init is working)
SPI (working but stmlib state)

stmlib state means that it works, but is rather complicated code that is
optimized for training not for speed or size.
